Sensata Technologies’ EXT 500 Series of circuit breakers are designed for wiring harness protection in 12 Volt automotive applications. The device protects circuits which occasionally experience momentary overloads and applications where self-resetting devices are preferred. The EXT 500 is sensitive to both over-current and over-temperature fault conditions. The unique arrangement of two opposing bimetallic elements results in a device that is insensitive to momentary overloads.

Sensata Technologies is an ISO and TS registered company providing world class quality products.

These curves are to be used only as a guide in selecting a protector for a
particular application. Factors such as distance from the heat source and
the method of mounting should be considered in selecting a protector. Final
trip times are dependent upon terminal configuration and mounting in the
application.

All Sensata Circuit Breakers do not contain any hazardous materials and are 100% in compliance with the Substance of Concern (SoC), ELV and RoHS directives.
